nice pic of your jag. i had one several years ago for a while. he was a mean little sucker! i liked him a lot! but my oscar you see pictured to the left is my baby and he has been my baby for 7 years now. like everyone else has said: dominance, stress, or a combination of the two. the blood parrots probably weren't in there long enough to really get their butts kicked. the jag would have done it eventually though, i can assure you. he was just stressed and trying to figure things out, then you took him and put him in a different tank: a very wise move on your part. the only fish i've ever had that was meaner than a jag was a black belt cichlid, and that thing kicked my oscar's butt so bad i had to take him back within 24 hours of buying him. he would act real polite when the tank light was on. then when the light went out, he'd turn into a ninja, man. the next morning i turned the light on my tank on and my oscar was nicked all up and down his body, and the black belt cichlid just looked at me like.......hmmmm, nothing to see here. i'm just minding my own business.....yeah, right......took his butt to the fish store for a refund immediately. nobody messes with tony like that ( my oscar).
